Conditions at La Bocana in September
September: Peak Storm Energy and Peak Messiness
September is the climatological apex of tropical cyclone activity in the Eastern Pacific, and La Bocana feels both the glory and the chaos. The average swell is a solid 4.5ft (1.4m) at 13.0s, but the directional spread is wider than any other month: SSW at 73%, SW at 16% and a notable 1.7% of waves in the 6.5-8ft (2-2.5m) range - the heaviest of the year. The downside is the wind: ideal conditions tie for the yearly low at 52%, with the rose dominated by E (12%), WNW (8%) and W (8%) as tropical systems swirl nearby. Rainfall peaks at 8.14mm/day, the water cools slightly to 29.9°C, and runoff from the Bocana river mouth can make the lineup murky. Pick your moments between storms and you'll find the heaviest surf of the season.
